Break is a keyword that breaks out of the code block, usually surrounded by braces, which it is in. In this case, break prevents the program from falling through and executing the code in all the other case statements. An important thing to note about the switch statement is that the ...
I passed a variable to switch, the value of the variable is 2 so the control jumped to the case 2, However there are no such statements in the above program which could break the flow after the execution of case 2. That’s the reason after case 2, all the subsequent cases and defaul...

由于case 1 包含 break 语句,只“穿透”到 case 1。 2.4 - 标签使用的整型表达式必须为常量 case 标签使用的整型表达式必须是常量表达式。 // A program with variable expressions in labels#include<stdio.h>intmain(){intx =2;intarr[] = {1,2,3};switch(x) ...
case 1: break; default: break; } 1. 2. 3. 4. 5. 6. 不过要注意,一旦加上了大括号,在case 0后面便不能访问到变量b了。 注意,如果上述代码以C方式进行编译,编译结果则会有所不同: main.c #include <stdio.h> #include<stdlib.h> int main(int argc, char *argv[]) ...
一、基本用法 switch语句在C语言中用于基于不同的情况执行不同的代码块。switch语句后面跟着一个控制表达式,这个表达式的值需要与每个case标签的值相匹配。如果匹配成功,程序就会执行相应的代码块。如果没有匹配的case,且存在default标签,那么会执行default标签后的代码。
In the following program, we use switch case statement to implement calculator. We read two numbers and a choice of operation from user. Based on the selected operation, the corresponding case block is executed. C Program </> Copy #include<stdio.h>voidmain(){inta;printf("Enter number, a ...
In Figure 4, 'switchval' (0) will first be compared to the constant in the first case statement (0). Since 'switchval' is equal to 0, the code on line 14 will execute and output 'code path executed for value 0'. Next, the 'break' statement on line 15 causes program to exit th...
